- This invention relates to a machine for use in cementing soles or halfsoleson shoes, particularly in connection with repair operations.- I

It is the object of my invention toprov-ide a machine for such purposesby which a shoe and to'a bracket 22 slidable on a cross bar 23, which acement-coated sole may be very quickly and conveniently placed underpressure and by which the pressure may be maintained for any desiredperiod. i a 3 A further object of the invention istoprovide a machinefor suchpurposes so designed that it is readily adaptable for use onshoes of widely differing shapes and sizes and for either whole l soleor half-sole operations. a

I have also provided improved devices iorhold ing and-supporting theshoe during. {the pressing operation. l

A I a Abell crank or handle 32-is provided for each pressing device and ispivoted on a-stud 33 mounted in bearings 34 on the under side of thetop.

frame member ;l2. ;A pair of links 35 are pivoted at 36 to each handle32 and are pivoted at By swinging the handleg32 from the position shownat the right in Fig. lto theposition shown at the leftin Fig. 1, the.shoe supports 20 and 28 are-moved downward and a shoe mountedthere- -1on is pressed against the cushion. I 4, which is .cess l3 and againstthe recessed base member I0.

' When thehandle'32 'is substantially in horizontal position; the lowerportion of the handle and the associated links 35 act as togg1e mem-vhers to hold the shoe supports and shoe positively. in the loweredposition indicated in :Fig. 6. Each sleeveis preferably provided withtransverse openings 40 and each plunger 31 is provided with acorresponding transverse opening in which balls 41 are mounted and arepressed When a sleeve30 isfiinoved to-raised position,

the balls fll enter the openings 40 in the sleeve ated parts in raised"position until the handle 32 1s againswung forcibly downward.

30 and releasably retain the sleeveand associa The machine maybe adaptedfor use on shoes of differentlengths by sliding-the br-acketi22. alongtheycro'ss bar 23 to? a position where the shoev is the recess 1 3 inthe base! 0, after. which the back or heel support .28 is movedtoutwjard toward the dotted l'ineposition in Fig.-2".until the heel ofagainsttheiront support 20.. 1

The front support 20 may be adapted to shoes having different shaped toeportions by providing aseparate toe piece 56 having a rib and slotconnection to the front end of the support 20, so that one toe piece 50may be removed and another toe piece of difierent outline may besubstituted, such a substituted toe piece being indicated at 58 in Fig.3.

The front shoe support 20 may also be made in two parts land 52 (Fig.3), theseparts being separable longitudinally and one part beingprovided with a lug or lateral projection 53 (Figs. 2 and 3) extendinginto a recess 54 in the other part and secured in adjusted position'by aclamping screw 55.

With this construction, the support}!!! may 'be widened or narrowed tofit different shoes and the toe portion may be adapted to differentwardly extended portion 6| of the support 20.

This overlapping feature permits a much wider range of relativeadjustment of the back support 28 and also provides asufficientlycontinuous surface for the shank portion of the shoe.

Forhalf-sole operations, the frontsupportiil may be used alone asindicated in Fig. 9, the back support 25 being removed. By adjusting thescrew 26 in the lower end of the sleeve 30, any desired final pressuremay be secured.

When the shoeis in the pressing position indicatedin Fig. 6, the rubbercushion i4 snugly engages the shoe sole or half-sole at all exteriorportions thereof and forces the same firmly against the sole ofthe shoe,in which position the sole is retained during the drying and setting ofthe cement. V

The sole-shaped depressions iii in the bottom of the recess I3substantially assist the operation by providing exceptionally heavypressure around the edge portionsof the sole where firm contact and atight joint is particularly essential.

.An important advantage of my improved pressing machine lies in the factthat no last is used and that no pressure is applied .to the shoe upperat any point, as has been the custom in machines previously used forthis purpose. The app1ica tionof pressure to the shoe upper quitecommonly results in injury to, the shoe, particularly toladies shoesformed of light or easily defaced materials. I

In the operation of cementing soles to shoes, particularly for repairpurposes, it is necessary to place the cemented parts under pressurewith the least possible delay if a firm and tight joint is to'beattained. Reference to the drawings will show that my improved. machineis particularly adapted for such rapid operation, as the front shoesupport 29 .may be adjusted in position before the shoe parts arecemented and the ad justment of the heel support 28 and downwardmovement of the lever 32 may be performed almost simultaneously and withgreat rapidity. r While I have shown my improved machine in duplex form,so: that a pair of shoesmay be conveniently cemented and pressed at thesame time, it will be obvious that a singlepressing' device may be madeembodying my improvements.

Having thus described my invention and the advantagesthereof, I do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what I claim is:

4. In a machine for pressing shoe soles, in combination, a verticallymovable member, a cross bar mounted thereon, front and back shoesupports mounted to slide relative to said cross bar, and means tosecure said supports in adjusted position, said supports havingoverlappingportions permitting extended relative longitudinal adjustmentwhile maintaining engagement thereof.

,8. In a. machine for pressing shoe soles, in combination, a verticallymovable member, a cross bar pivoted thereto, a bracket slidable thereon,means to secure said bracket in adjusted position, and-a frontshoesupport pivoted to said bracket, said shoe support being shaped tosubstantially conform to the front and shank pore tions of a shoemounted thereon.
